  • Externalizing the Autopoietic Part of Software to Achieve Self-Adaptability
    2011 IEEE World Congress on Services, 2011
    Co-Authors: Romina Torres, Hern´n Astudillo
    Abstract:

    The autopietic/allopietic duality has been proposed to address the fact that Software systems must look to their own survival besides their successful mission completion. To the best of our knowledge, there are no explicit computational models to operationalize and test this distinction. This article describes a framework to add autopietic capabilities to composite Software systems, by using an external self-Organized Market full of service providers willing to provide services for satisfying new requirements and recovering actions. The approach is exemplified when a QoS agreement violation occurs in a composite application system.

  • A Market approach to long-term security of supply
    IEEE Transactions on Power Systems, 2002
    Co-Authors: C. Vazquez, M. Rivier, I.j. Perez-arriaga
    Abstract:

    The problem of ensuring that there is enough generation capacity to meet future demand has been an issue in Market design since the beginning of the deregulation process. Although ideally the Market itself should be enough to provide adequate investment incentives, there are several factors that prevent this result from being achieved, and some actual Markets have already experienced problems related with a lack of generation capacity. A regulatory framework to address this question is presented. The procedure is based on an Organized Market where reliability contracts (based on financial call options) are auctioned, so both their price and their allocation among the different plants are determined through competitive mechanisms. This results in a stabilization of the income of the generators and provides a clear incentive for new generation investment, with a minimum of regulatory intervention. Additionally, the method represents a Market-compatible mechanism to hedge demand from the occurrence of high Market prices.

  • Trust in Trading Relationships: The Case of the Kribi Fish Market
    2014
    Co-Authors: François Tiotsop, Patrice Guillotreau, Juliette Rouchier
    Abstract:

    The Marketing of fresh fish in Kribi, Cameroon, faces many uncertainties and implies the use of specific assets. The industry players have put in place hybrid coordination mechanisms centered on contractual arrangements that rely heavily on trust. The recent implementation of an Organized Market, which was designed to foster transparency in transactions, has reduced the importance of social networks. However it cannot be said that inter-individual trust has been entirely replaced by the mechanism of competition.

  • Le rôle de la confiance dans les relations d'échange : le cas du marché de poisson de Kribi
    Revue Française de Socio-Économie, 2014
    Co-Authors: François Tiotsop, Patrice Guillotreau, Juliette Rouchier
    Abstract:

    The Marketing of fresh fish in Kribi, Cameroon, faces many uncertainties and implies the use of specific assets. In this chain, actors build hybrid coordination mechanisms, with contractual arrangements which rely heavily on trust. The recent implementation of an Organized Market, which was designed to foster transparency in transactions, has reduced the role of network linkages. However it cannot be said that inter-individual trust has been entirely substituted by the competitive mechanism.
